Questions
How big is the CC M7 PCB?
It measures 40 × 65 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CC M7 use?
138 parts, built around the NRF21540-QDAA-R7, BMP581, ICP-20100 and TPS566242DRL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the CC M7 KiCad files?
From the OzanE1/CCM7A repository on GitHub, at the commit this page was made from: the board is CC_M7/CC_M7.kicad_pcb and its schematic CC_M7/CC_M7.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CC M7 design in my own project?
Its repository publishes it under the LGPL-2.1 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
